Jack I am a principal commercial broker and retail real estate developer.

First if the mortgage payment is being paid by tenants and you are only paying taxes and insurance and repairs you are probably spending less than you could rent for.However the big thing is that every month you pay the mortgage payment some of the money goes towards principal. 

Lots of principal paymon every month now, almost $800 a month and growing!

Not enough brokers and agents invest themselves.They are married to the job making them a living instead of their investments giving them their financial freedom.I am a principal broker on the commercial side 13 years into the business.

As an investor your profit/gain is a function of one of two things (c) principal amount of loan and (d) interest accrued.  

So you call the bank that holds the note on your mortgage, and tell them you want to make a $5,000 principal payment.

Your great interest rate gives you over $600 of principal pay down, but that works out to barely 7% annual ROI.

I had a couple of thoughts on this, and wanted to see I might be able to get some advice... 1. pull together enough cash to just pay cash for the next 1 or 2 houses. ... the drawback to this is that may take a little while, and many lower cost ones are either in rough areas or need substantial work to make them rentable. 2. switch my focus to searching for a 5+ unit multifamily.  

If the trustee is a legal entity, it must have a principal place of business in Delaware.

When filing last year's taxes all of the rental income was shielded by writing off losses via a combination of depreciation, loan interest, fees for loan origination, other closing costs etc.It got me thinking though as time goes on the amount of interest that I will be able to write off will decrease as more of my mortgage payment is on principal and not interest.
